PATENT OFFIC WILLARD H. BROWNELL, OF BATTLECREEK, MICHIGAN.

ERAS ER-TIP. FOR LEAD-P ENCILS.

SPECIFICATION forming part of Letters Patent No. 737,070, dated August25, 1903; Application filed April 21, 1902. Serial No- 103,949. (Nomodel.)

To all'whom it may concern.-

Beitknown thatLWILLARD HJBROWNELL, a citizen of the United States,residing at the city of Battlecreek, in the county of Calhoun and Stateof Michigan, have invented a certain new and useful Eraser-Tip forLead-Pencils, of which the following is a specification.

This invention relates to'rubloer tips for lead-pencils. I 7 j;

The object of the invention is to provide an improved rubber or similarelastic eraser-tip for lead-pencils with a secure retaining means,whereby an elongated piece of erasive material can be made use of andquickly and easily adjusted to compensate for wear or to protect thesame, thus making it entirely practical to make use of a superiorerasive material, as the same can be transferred from pencil to pencilas the same are used up.

Further objects will definitely appear in the detailed description tofollow.

I accomplish the objects of my invention following specification.

The invention is clearly defined, and pointed out'in the claims.

A structure. embodying the features'of my invention is fully illustratedin the accompanying drawings, forming a part of this specification, inwhich- Figure 1 is an enlarged view of the structure embodying thefeatures of my invention. Fig. 2 is an enlarged detail view of the same,the pencil and erasive material bein shown' in full lines.

In the drawings similar letters of reference refer to the similar partsin both views.

Referring to the lettered parts of the drawprojecting teeth or lugs Fare formed in the upper part of the sleeve A by indentations in thesleeve, and outwardly-projecting lugs D are formed by stamping the metaloutwardly.

Outside of the sleeve A, I provide an adj ustable sleeve or cylinder 0.This sleeve is formed with a spiral groove or thread G, adapted toengage the lugs D, so that the cylinder C may be screwed up and down onthe sleeve A. A lug I-I limits the-downward movement of the cylinder 0.When the cylinder G is screwed or forced outwardly, it forces the jaws Finto the erasive material E and securely retains the same in position.It is apparent that byadj usting the outer sleeve the erasive materialcan be quickly and easily adjusted in any position desired.

I claim as new, and desire to secure by Letters Patent, is-

1. In a pencil-tip, the combination of a sleeve A, slotted at one end asat I to receive the end of a lead-pencil, and at the other end, as at B,to receive an elongated piece of erasive material; inwardlyprojectingjaws F formed on said sleeve adapted to engage said erasive material;outwardly-projecting lugs D formed in said sleeve; and an adjustable.

external cylinder 0 having a spiral groove G adapted to engage said lugsD, whereby the same may be adjusted back and forth on said sleeve, forthe purpose specified.

2. In a pencil-tip, the combination of, a sleeve A, slotted at one endto receive the end of a leadpencil and'at the other to receive anelongated piece of erasive material; jaws formed on said sleeve adaptedto engage said erasive material; suitable guides on said sleeve A; andan adjustable external cylinder 0 having threads adapted to engage saidguides, whereby it may be adjusted back and forth thereon, for thepurpose specified.

In witness whereof I have hereunto set my hand and seal in the presenceof two witnesses.
